FBG filter

Electric tunable fiber Bragg grating filter

Xiaoxiao Photon's tunable fiber Bragg grating filter (OETFG-200) can provide a stable adjustable range, simple structure, high resolution, and long lifespan. This adjustable filter adopts Fiber Bragg Grating (FBG) technology, which can be used for both transmission mode and reflection mode, or only for reflection mode (as required). As an option, a fiber optic circulator can be integrated to provide a bandpass signal for the output port. The cyclist can be used in the range of 1060nm, 1310nm, and 1550nm. The band stop option without the need for a loop protector is also available. In the bandstop version, the communication signal is reflected to the input end.

Standard narrow linewidth passband fiber grating filter

Xiaoxiao Photon's OEPBG-100 standard narrow linewidth passband filter is based on advanced fiber Bragg grating technology. This type of filter can be used to select a small bandwidth optical signal to pass through while blocking all other wavelengths. This narrow line broadband filter can be applied in fields such as ASE noise suppression in fiber lasers, laser radar filters, high-resolution Raman spectroscopy, fluorescence microscopy, and optical instruments.

Ultra narrow linewidth passband fiber grating filter

Xiaoxiao Photon's OEUBG-100 ultra narrow linewidth filter based on fiber Bragg grating is a cutting-edge optical component designed to provide wavelength selectivity with high transmission efficiency. With extremely narrow bandwidth, it isolates specific wavelengths with high precision, making it highly suitable for applications such as spectroscopy, laser systems, and telecommunications. Due to their excellent performance in suppressing unwanted spectral noise, they are crucial for high-resolution systems that require precise control of transmission wavelengths.

Thermally tunable fiber Bragg grating filter

The temperature tunable fiber Bragg grating filter (OETFG-300) of Xiaoxiao Photon utilizes a thermoelectric cooler (TEC) to fine tune the center wavelength of FBG in the range of 1 nm. The specifications of fiber Bragg grating (FBG) filters can be fully customized and defined by customers (with some limitations in application). When in reflective mode, the customer needs to use an external optical ring resonator. The circulators can be obtained from Xiaoxiao Photon in the range of 1060nm, 1310nm, and 1550nm, and can be provided upon request.
